I've started the process of fetching over all the articles and tutorials from Revit Zone to revit.biz.

I think it would be far better to have all that info in one place. There is well over 2 years worth of content on Revit Zone! The process is taking a while as I have to ensure all the backlinks on any referring sites and at Google will all forward to the new page at revit.biz. This means setting up an automatic "301 Redirect" for each page that has moved across. Without this, Google will see 2 copies of the same page on 2 different sites and the Google Gods will defintiely NOT be happy about that!
